a 48-year-old male patient presented to the emergency department with the complaints of epigastric pain and melena for the past 3 days. the pain was started suddenly and has progressed and after a while, he passed melena stool. he also mentioned some episodes of vomiting that was not bloody. the pain score was about 8/10 (based on verbal quantitative scale) and slightly radiated to back. he loo...

We describe two patients, with no previous history of vascular problems but poor lung function, who experienced septic shock due to bowel ischemia. Both were fed an enteral formula rich in fiber using a feeding tube and experienced septic shock with regular enteral feeding. Surgical finding showed hemorrhagic ischemia in the bowel. The pathologic finding suggests these changes may have been due...

BACKGROUND Intestinal ischemia is a common complication of intestinal obstruction and arises from impaired perfusion. The resultant local and systemic inflammatory response and bacterial translocation come with a significant degree of morbidity and mortality. This study therefore aimed to investigate the predictive value of elevated levels of serum lactate and phosphate as biomarkers of intesti...

We report a case of small bowel ischemia secondary to sickle cell disease. Acute bowel ischemia is an uncommon presentation of patients with sickle cell disease. Historically, only a handful of cases have been reported. We also provide a summary of the literature relevant to sickle cell patients with acute bowel ischemia.

PURPOSE To analyze the CT findings in 20 cases of complicated small bowel obstruction with surgically and histopathologically proven small bowel ischemia, caused by extrinsic venous outflow obstruction of the affected bowel loops and to discuss the question, if bowel wall thickening, abnormal bowel wall enhancement, ascites and mesenteric stranding correlate with the severity of bowel wall dama...

We report an usual case of hepatic portal venous gas (HPVG) in the setting of acute pancreatitis and small bowel ischemia. Interestingly, the HPVG disappeared within 2 hours of the original computed tomography scan, despite the patient having small bowel ischemia. The patient had a complicated clinical course, dying 62 days postadmission. This case highlights that HPVG in setting of acute pancr...

BACKGROUND Intestinal ischemia is an abdominal emergency that accounts for approximately 2% of gastrointestinal illnesses. It represents a complex of diseases caused by impaired blood perfusion to the small and/or large bowel including acute arterial mesenteric ischemia (AAMI), acute venous mesenteric ischemia (AVMI), non occlusive mesenteric ischemia (NOMI), ischemia/reperfusion injury (I/R), ...

Small bowel feces sign (SBFS) is a computed tomography (CT) finding that appears as fecal like material in dilated small bowel loops. This sign is usually seen in association with gradually progressive small bowel obstruction. We present a case of occlusive mesenteric ischemia in which the SBFS appeared on CT scan early on in the course of the disease. We put forward a suggested alternative mec...

OPIOIDS are known to reduce the motility of both the colon and the small intestine. However, some investigators have reported, both in animal models and in humans, that morphine increases duodenal motility. In vivo studies of the effect of morphine on small bowel motility are complicated because most have been performed in the postoperative period, where the additional trauma of laparotomy and ...
